Flash Powder and Blasting Cap


Hello ,
A friend of mine recently told me that he is using small amount of primary in Al Foil to detonate his KClO4 / Dark Al / S flash powder with greater results than just a fuse. Any more info on this ?

Nope. But why :)? Would be interesting to try. But sulfur does increase the sensitivity a bit. A good bit.
Regular FP is quite powerful. Underestimated. There are much more powerful variants that are even insensitive to flame and static... but I am not ready to share them.

Dornier told me about Shimizu's book once. In the book he shows some tests he did and he find out that 64 KClO4 , 23 Dark Al and 13 S will give the loudest report. Since then its the only KClO4 comp im using with success. It wont even go off with a hammer hit

It is loud!

I didn’t know it was insensitive. Thank you for the info!

What would be most interesting would be replacing half of the kclo4 with AN and detonating.

The papers I've read place KClO4 flash powders at 80 % of TNT in far field impulse.

AN/Al 75:25 is at the very least 120 % of TNT or half more powerful than flash. If you have a blasting cap, slightly thermobaric ammonals are far better, safer, more powerful and cheaper than flash.

I made such mix: AN/Al/C 72:25:3 and once was able to initiate it with the aid of smoke powder (but only once). Later I mixed ammonium picrate with Al and AN. But some powerful detonator is a must. This mix is very insensitive.
